    Abstract: According to one or more aspects of the present disclosure, operations may include obtaining multiple microphone signals derived from a microphone array that includes a multiple omnidirectional microphones. Each of the microphone signals may be derived from a different microphone of the microphone array. The operations may further include determining whether the microphone signals include noise, such as wind noise, based on two or more of the plurality of microphone signals. In addition, the operations may include generating an output signal based on a beamformed signal or a reduced-noise signal based on whether the microphone signals are determined to include noise.

    Abstract: Disclosed herein are methods, systems, and devices for mitigating the impact of noise, such a low-frequency noise caused by wind, on sounds received at a hearing prosthesis. An example method includes receiving an external sound signal transduced externally to a recipient from an ambient sound and an internal sound signal transduced internally to the recipient from the ambient sound. The example method also includes determining that a triggering condition is present in the external sound signal. The triggering condition may be indicative of a condition in that more adversely affects externally-received sounds than internally-received sounds. In response to determining that the triggering condition is present in the external sound signal, the example method further includes generating a stimulation signal that is based at least in part on spectral information of the internally-transduced sound.

    Abstract: A method of wind noise reduction. Left side and right side microphone signals are obtained. In a first stage wind noise reduction is applied to a first sub-band of one of the signals, below a spectral threshold NA. In a second stage the wind noise reduced first side signal, and the second side signal, are both split into a sub-band below a threshold NB less than NA. The sub-band of the first side signal is mixed with the sub-band of the second side signal to produce an aggregate third sub-band signal having reduced wind noise, which is recombined with the respective sub- bands above the threshold NB to produce output first and second side signals.

    Abstract: A method of processing digitized microphone signal data in order to detect wind noise. First and second sets of signal samples are obtained simultaneously from two microphones. A first number of samples in the first set which are greater than a first predefined comparison threshold is determined. A second number of samples in the first set which are less than the first predefined comparison threshold is determined. A third number of samples in the second set which are greater than a second predefined comparison threshold is determined. A fourth number of samples in the second set which are less than the second predefined comparison threshold is determined. If the first number and second number differ from the third number and fourth number to an extent which exceeds a predefined detection threshold, e.g. as determined by a Chi-squared test, then an indication that wind noise is present is output.
